Pressure flushing device for closets.

PRESSURE FLUSHING DEVICE FOR CLOSE'IS.

Specification of Letters Patent.

Patented June 2., 1914..

Application filed November 29, 1912. Serial No. 734,023.

My invention consists of a flushing receptacle provided with a suitableball valve, the parts being constructed and arranged as hereinafter moreparticularlyexplained.

Figure 1, is a side elevation of my im proved flushing device. Fig. 2,is a vertical section. Fig. '8, is a vertical section at right angles toFig. 2. Fig. 4, is a detail of the operating lever.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the top of a closet bowl and B is the receptacle, which is fastenedto'the top A by'a flange B through which extend suitable bolts 13 intothe top of the bowl A.

The valve chamber B is providedv with a curved portion B at one side, anupper curved. portion 13* and a-curved portion B opposite the curvedportion B The curved portions 13* and B terminate in a flange B to whichis secured a circular plate C interiorly threaded and into which extendsthe threaded end of the inlet pipe '1).

B is an inwardly extending flange upon which rests a yielding seat Epreferably of rubber.

F is the ball valve.

G is the operating lever, which is operated through a handle H.

I is a sanitary device, which is connected by a pipe I to the valvechamber B, and

by a pipe I to the passage-way B leading down into the bowl.

The operation of my sanitary device I do not describe as it forms thesubject matter way 13 leading to the bowl.

The shifting lever G is made as shown in Fig. 4:. The spindle of thehandle H passing through the slots G. The shiftinglever is provided witha stop G to limit its backward throw and a lug G to operate against theball to primarily unseat it to relieve-the pressure. The end edge Grforms a final means of throwing the ball into theposition shown indotted lines. It will be noticed that the lever G is dished and it willbe consequently understood that when the water passes downwardly betweenthe balland the lever it serves to help to quickly restore the lever toits normal position on account of the pressure that the water will exerton the dish form.

The operation of my invention is as follows: The lever G is manipulatedso that the lug G first acts on the ball and temporarily relieves thepressure. The edge G of the lever then contacts with the ball and throwsit into the position shown in dotted lines in Fig. 2, thereby allowingthe full pressure of the water to pass through the flanged orifice BUpon the release of the handle H the lever G assumes its normal positionbeing helped therebv by the pressure of the water on the dished surfaceand the ball is likewise by the suction and pressure restored to thenormal position on its seat. Before the ball is fully seated the waterbeing at a very slight pressure passes through the pipe 1 into thesanitary device and back through the pipe I into the passasreway 13leading to the bowl. such water being surcharaed with the disinfectingfluid or chemical in the sanitary receptacle or device therefor.

From this description it will be seen by this form of flush for closetsI eliminate all therefor and a limiting lug at the upper end flushingtanks and obtain the pressure direct of the lever, and a valve openinglug near 10 from the main.

What I claim as my invention is. 5 The combination with the valvechamher having a suitable discharge orifice and a the lower end in thedished portion, as and for the purpose specified.
